Owned by logger cable... WHY!!!!!

[selmerguy]

Why is this logger cable owning me? I have re made it 3 times and it wont work. I figure it shouldnt be that hard to make one. I am trying to log with a laptop so I switched pins 2 and 3 so the dioed is on pin 3 and the resistor is a 10k from radio shack. Here are the pics. I just used some extra plugs on the ends for testing. Does everything look right?

Is the diode the right way? They are directional you know.

black line tward the wire

You have the pins on the serial connector backwards.
I assume you are using a female connector.
You are connected to pins 1,3 and 4.
Shound be pins 2,3 and 5.

That's what it looks like from here.

Thanks guys. it was wrong. Thats what I get for looking at pics of the cable on the writeup and not matching pins. Works great now.

his diode was installed correct, the anode needs to be more positive than the cathode in order for them to conduct

unless its a zener diode, than you just might want to make sure its in 'backwards'
